Apparently, Harry will be ringing in his 21st year with model Nadine Leopold.

“Everyone’s teasing him, saying he’s in love, and he’s not denying it,” a source told The Sun. “It’s the real deal. He’s never felt this way about anyone before.”

They added, “Harry has spent virtually all his free time in Los Angeles with Nadine. They’re infatuated with each other and can’t stand being apart. There’s nobody else he’d rather be with on his birthday.”
